To all whom it may concern:

Be it known that I, HENRY A. HATFIELD, a citizen of the United States ofAmerica, residing at Clarkson, in the county of Gray- 5 son and State ofKentucky, have invented new and useful Improvements in Motors, of whichthe following is a specification.

This invention relates to motors designed especially for impartingreciprocatory motion to churn dashers, cutting devices and otherelements which have' reciprocatory action.

The accompanying drawing shows a perspective view of my improved motoras arranged for use for operating the dasher of a churn.

Ieferring to the drawing, the numeral 1 designates a suitable bedpieceor platform, I to which is secured a rectangular base 2,

triangular supporting standards 3, each composed of'a pair of side rodsor bars 4, an intermediate rod or bar 5, said bars being suitablyconnected at their lower ends to the base 2 and joined at'their upperends, and a cross bar 6 with bearings thereinuniting and staying thebars at a suitable elevation above the base. The two standards areconnected at their up er and lower ends by tie rods 7 andf8, whlcmaintain them in fixed relation.

Mounted in bearings cross-bars 8 formed or rovided upon the up er endsofthe standar sis a main drive sha t 9, which is extended'at its endsbeyond said standards and carries at one end a balance or iy wheel 10.The other end of the shaft is bent to form a crank 11 carrying a slidingsleeve 12 adjustably secured thereto by a set screw 13 and carrying awristl pin 14 threaded for the reception of a nut 15. The shaft 9 may bedriven through the medium of any preferred driving mechanism, but isshown in the present instance arranged for operation from a Vdrivingshaft 16 journaled in bearings formed at the intersection of the mainbars of the standards with the cross bars 6. The shaft 9 carries apulley 17 connected by a belt 18 with a pulley 19 on the shaft 16, andthe latter is provided with an actuating crank`20, whereby it may bedriven directly by hand power.` The shaft 16 is further provided with a-crank bend 21 operatively connected by a pitman or connecting rod 22with a treadle 23\fulcrumed on the rod 8, whereby the operatingmechanism may-be slams mitm? from the sides of which rise substantiallyactuated-bly foot Vpower, desired," or both hand and foot power throughthe medium of the -said treadle and the crank 20.

rmly clamped in .operative position by a clamping device composed ofrods 26 hinged at their lower ends t'o the latforni, and a transverserod 27 provide with terminal elyps engaging the rods 26, which latterare t eaded at their u per ends for the reception of nuts 28.` he rods26 engage and confine the churn body in lace, while the rod 27 extendsacross and c amps the lid to said body. Arran ed on therods 26 above theends of the ro 27 are coiled springs 29 `which` exert a yieldingclamping pressure against the rod 27 and are held 1n position by thenuts 28, whereby the ressure of said s'prings may be varied tp c amp thechurn pody and its lid with the desired degree of orce.

The dasher rod 30 is operatively connected by a pitman with the crank ofthe shaft 9, said pitman being composed of two sections, namely, a rod31 ivotally engaging the wrist pin 14 and co ed thereon by thenut 15 anda sleeve section 32 `jointed to the lower end of said rod, as shown at33, and receiving the upper end of the dasher rod 30, to which it issecured byr a set screw 34. By this construction the pitman is adaptedfor connection with long or short rods, and also through suchconstruction and the construction of the parts 11, 12, and 13 the throwor action of the driving crankmay be varied to vary the stroke oftheitman and dasher.

It will thus be seen t at the invention provides a'sim le .and effectiveconstruction of motor whic may be employed for actuating churn dashersand other reciprocating devices and which is adjustable for connectionwith long or short operating rods and also to vary the stroke or extentof movement of the operated part as circumstances may require. Havingthus described the invention, what I claim is: e

' A motor comprising a basewith standards rising from the opposite sidesthereof, intervmediate bars likewise secured to the base and 'grouped attheir upper ends with seid 'stndards brace rods at the u per and lowerends l if-'Stile standards, crossars with bearings 5 therein .secured atsuitable distances apart to the-standards and said intermedi-ate bars,drive shafts mounted respectively. in' the bearings of the cross-bars, epulley on each' of said shafts, a belt connecting said pulleys,

the up er shaft.' having a crank-arm, and 1'0 means or driving the lowershaft, substantially as specified. ,v p

In testlmony whereof I hereunto ax my signature invpresence of twoWitnesses.
